OK, a guy here has a melamime(spelling) rack for sale and i am not sure its worth what he is asking.Its a seven tub rack (41 or 42 quart size)with 11" flex watt installed allready all i need to do is plug it into my thermostate.Its large enough for adult ball pythons.He is asking $100 for it as is.I am not sure how long he used it.I have no idea how long flex watt will last or how much Melamine costs to just build one.I just do not want to buy a used one and have to spend more money to replace the flex watt right off the bat.I am on a tight budget as it is .So i come to ask my reptile internet family for your opinions .Thanks
